Question

11. Resolva as operações:
a)-7-8-
g) (- 12).(-5)
b) - 9 + 5 =
h) (-70 ): (+35) =
c)-3-10 =
1) (+195): (+13)-
d) + 9 + 11 =
1) (+38).(-12)=
e) 15 - 15 =
f) - 13+7=​

Answer 1

-7 - 8 = 1

(-12).(-5) = -60

-9 + 5 = -4

(-70):(+35) = -2

-3 - 10 = 7

(+195):(+13) = 15

+9 + 11 = 20

(+38).(-12) = -456

15 - 15 = 0

-13 + 7 = -6
